Molding for automotive front glass and molding apparatus
Abstract
An automobile windshield molding is provided to be fitted in a
gap formed between an automobile window frame and an automobile
windshield. The molding includes an upper molding and opposing side
moldings formed monolithically and continuously with the upper
molding. The portions of the upper and side moldings which extend
above the windshield are formed thicker for the side moldings than
for the upper molding, in order to prevent sideways scattering of
water incident on the windshield. The thickness of the side
moldings decreases gradually toward the upper molding. The molding
can be formed by a molding apparatus utilizing shutters which have
predetermined shapes and which are linearly movable in order to
increase or decrease the effective size of the extrusion opening to
gradually change the thickness of the moldings during continuous
molding of the upper and side moldings.

Description
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a molding for an automotive front
glass (i.e. a windshield molding) and a molding apparatus therefor
and more particularly to a molding to be fitted into the gap formed
between the peripheral edge of an automotive front glass and a
window frame of an automotive body in order to fill up the gap and
simultaneously decorate the gap portion.
2. Prior Art
As shown in FIG. 20, a molding of the sort recently used for a
front glass (hereinafter called simply the `molding`) is such that
the side moldings 62a fitted to both sides of a front glass 61 are
provided with rainwater guide grooves 63, respectively.
The rainwater guide grooves 63 are provided so as to prevent
rainwater from sticking to the front glass 61 during traveling and
then scattering and hence penetrating into the driver's seat and
also to prevent the visibility range from being obstructed by the
rainwater sticking to the front glass 61.
However, since the side molding 62a fitted with the rainwater guide
groove 63 is not usable in the upper portion of the front glass 61,
an additional upper molding 62b without such a rainwater guide
groove 63 is fabricated and coupled to the side moldings 62a by
means of corner joints 64. As a result, the conventional molding
has been composed of five parts: two side moldings 62a, one upper
molding 62b and two corner joints 64.
Consequently, the conventional construction stated above results in
an increased number of parts and thus an increase in the amount of
labor for assembly, thereby increasing production costs. Moreover,
as it is hard to make luster and color tones of the corner joints
64 strictly harmonize with those of the side and upper moldings
62a, 62b, the external appearance deteriorates as the junctions
become easily recognizable. In addition, there is formed a gap
between the corner joint 64 and each of the moldings 62a, 62b and
the gaps tend to allow damage to develop.
SUMMARY OF THE INVENTION
A molding according to the present invention is characterized in
that side moldings to be fitted to the respective side edges of a
front glass and an upper molding to be fitted to the upper edge
thereof are made continuous by monolithic molding; the wall
thickness of the side molding is made greater than that of the
upper molding to the extent that rainwater sticking to the front
glass can be prevented from scattering sideways; and the wall
thickness of the ornamental portion of the side molding in each
corner portion of the molding is gradually made smaller toward the
upper molding. In this molding, a groove lip is projected inwardly
toward the upper end of the ornamental portion and a rainwater
guide groove is formed between the groove lip thus projected from
the ornamental portion of the side molding and the front glass,
whereas the groove lip projected is caused to resiliently contact
the front glass so as to not form a rainwater guide groove in the
ornamental portion of the upper molding, whereby the rainwater is
effectively prevented from scattering because of the function of
the rainwater guide groove. When the rainwater guide groove is
provided in the upper molding, the wall thickness of the ornamental
portion thereof can be made smaller.
With the molding according to the present invention, the gap formed
between the peripheral edge of the front glass and the window frame
of the body is closed by one continuous molding as the side and
upper moldings are monolithically molded. Consequently, no
junctions are necessary in the corner portions of the molding
because corner joints can be dispensed with and its external
appearance as well as its strength is thus improved. Moreover, the
number of parts to be molded is decreased to one and this results
in not only a decrease in the amount of labor for assembly but also
in a reduction in cost.

DETAILED DESCRIPTION OF THE INVENTION
FIGS. 1 to 8, inclusive, show a molding M.sub.1 and a molding
apparatus embodying the present invention.
The molding M.sub.1 is a combination of side moldings M.sub.1 a and
an upper molding M.sub.1 b that have been molded by a molding
apparatus monolithically and continuously, the side moldings being
fitted to peripheral edges on both sides of a front glass 10, the
upper molding being fitted to the upper edge thereof.
Each of the side and upper moldings M.sub.1 a, M.sub.1 b is
composed of an ornamental portion 2 with a groove lip 1 projecting
inwardly at its upper end and a clip fitting portion 3 formed by
bending a thin metal sheet and secured to the outside face of the
ornamental portion 2. However, the wall thickness T.sub.1 a of the
ornamental portion 2 of the side molding M.sub.1 a is made far
greater than the wall thickness T.sub.1 b of the ornamental portion
2 of the upper molding M.sub.1 b (see FIGS. 3 and 4). A small lip 4
is secured to the outside of the clip fitting portion 3, the small
lip 4 and the ornamental portion 2 being molded out of elastic
material such as rubber.
As shown in FIGS. 3 and 4, U-shaped clip mating pieces 7 are
secured via a double-sided tape 6 to the tilted portion 5a of a
body panel 5 at predetermined intervals. T-shaped clips 8 are
fitted to the clip fitting portion 3 forming the molding M.sub.1 at
predetermined intervals. The clip mating pieces 7 and the clips 8
are provided with mating teeth 7a, 8a formed thereon,
respectively.
To fit the molding M.sub.1 into the gap 9 formed between the window
frame of the body and the peripheral edge of the front glass 10,
the front glass 10 is first secured via a sealant 11 to the body
panel 5 of the window frame. When the molding M.sub.1 is
subsequently forced into the gap 9, the mating teeth 8a of the clip
8 fitted to the molding M.sub.1 and the mating teeth 7a of the clip
mating piece 7 fitted thereto mate with each other as shown in
FIGS. 2 to 4. Then the lower end face of the ornamental portion 2
of the side molding M.sub.1 a resiliently contacts the surface of
the front glass and simultaneously the inwardly projecting groove
lip 1 of the ornamental portion 2 of the upper molding M.sub.1 b
resiliently contacts the surface of the front glass 10, whereby the
gap 9 is filled up (or closed) as the molding M.sub.1 is fitted
into the gap 9.
A rainwater guide groove 12 is formed between the groove lip 1
projected inwardly at the upper end of the ornamental portion 2 and
the surface of the front glass 10 in the side moldings M.sub.1 a.
However, such a rainwater guide groove 12 is not formed in the
upper molding M.sub.1 b as the groove lip 1 resiliently contacts
the surface of the front glass 10. In a corner portion M.sub.1 c
forming the junction between the side molding M.sub.1 a and the
upper molding M.sub.1 b, the wall thickness of the ornamental
portion 2 of the side molding M.sub.1 a is made gradually smaller
toward the upper molding M.sub.1 b, whereas the width W (see FIG.
3) of the rainwater guide groove 12 is made gradually smaller so
that the guide groove disappears where it joins the upper molding
M.sub.1 b. In FIGS. 2 to 4, numeral 13 denotes dam rubber for
preventing the sealant 11 from flowing out.
The molding apparatus for the molding M.sub.1 will be described
with reference to FIGS. 5 and 6.
A molding die 14 is provided with an extrusion molding port 15
substantially corresponding in configuration to the section of the
side molding M.sub.1 a. A first and a second shutter 16, 17 are
provided in the front portion of the die 14 in such a way as to
partially cover the extrusion molding port 15. The first shutter 16
is linearly movable along the direction P corresponding to the wall
thickness of an opening 15a for extruding the ornamental portion 2
of the molding M.sub.1 out of the extrusion molding port 15. The
second shutter 17 is linearly movable along the direction Q of an
opening 15b for extruding the groove lip 1 of the molding M.sub.1
out of the extrusion molding port. The shutters 16, 17 are arranged
so that they are respectively linearly guided by the shutter guides
18, 19. The shutters 16, 17 are also equipped with drive motors 21,
22 and conversion mechanisms 23, 24 for converting rotational
movements to linear movements, respectively.
In FIGS. 5 and 6, numeral 15c refers to an opening for extruding
the small lip 4, and 15d to an opening (slit) for passing
therethrough the metal sheet for molding the clip fitting portion
3.
The effective extrusion opening for the side molding M.sub.1 a is
shown by a continuous line in FIG. 5, whereas the effective
extrusion for the upper molding M.sub.1 b is shown by a two-dot
chain line in FIG. 5 and a continuous line in FIG. 6.
In order to transfer from the process of molding the side molding
M.sub.1 a to that of molding the upper molding M.sub.1 b, as
exemplified in FIGS. 7 and 8 (A denotes the transfer portion in
FIGS. 7 and 8), the first and the second shutters 16, 17 are
gradually linearly moved from the state shown in FIG. 5 in the
directions of arrows P and Q, respectively. The wall thickness of
the ornamental portion 2 is thus made gradually smaller, whereas
the projected length of the groove lip 1 is gradually decreased,
whereby transfer to the molding process of the upper molding
M.sub.1 b is accomplished.
On the other hand, to transfer from the process of molding the
upper molding M.sub.1 b to that of molding the side molding M.sub.1
a (B denotes the transfer portion in FIGS. 7 and 8), the first and
the second shutters 16, 17 in the state of FIG. 6 are gradually
linearly moved in the directions opposite to the arrows P and Q,
respectively. The wall thickness of the ornamental portion, 2 is
thus made gradually greater and when the first shutter 16 reaches
the end of its retraction, the ornamental portion 2 having a
constant wall thickness is formed, whereas the projected length of
the groove lip 1 is gradually increased, whereby when the second
shutter 17 reaches the end of its retraction, the groove lip 1
having a constant projected length is formed.
FIGS. 9 to 12, inclusive, show another molding M.sub.2 and its
molding apparatus embodying the present invention, wherein like
reference characters designate like or corresponding parts of the
molding M.sub.1.
The molding M.sub.2 is constructed so that rainwater sticking to
the front glass 10 is prevented from scattering sideways by merely
increasing the wall thickness of the ornamental portion 2. No
groove lip 1 is provided in the ornamental portion 2 as in the case
of the molding M.sub.1.
More specifically, the clip fitting portion 3 formed by bending the
metal sheet is secured to the outer face of the upper end portion
of the ornamental portion 2 in such a manner that it is embedded
therein in a side molding M.sub.2 a, whereas the small lip 4 and
the ornamental portion 2 are monolithically molded. The molding
M.sub.2 is fitted into the gap between the peripheral edge of the
front glass 10 and the window frame by mating a clip 8' inserted in
the clip fitting portion 3 with the clip mating piece 7 secured to
the body panel 5 of the window frame. In the side molding M.sub.2
a, moreover, the wall thickness T.sub.2 a of the ornamental portion
2 is much greater than the wall thickness T.sub.2 b of the
ornamental portion 2 of an upper molding M.sub.2 b. The wall
thickness T.sub.2 b of the ornamental portion 2 of the side molding
T.sub.2 a is made great enough to prevent rainwater on the front
glass 10 from scattering sideways. Rainwater can be prevented from
scattering, if the wall thickness is greater than 8 mm.
As shown in FIG. 9, the wall thickness of the ornamental portion 2
of the side molding M.sub.2 a is made gradually smaller toward the
upper molding M.sub.2 b in the corner portion M.sub.2 C of the
molding M.sub.2, whereby the side molding M.sub.2 a and the upper
molding M.sub.2 b are made consecutive and continuous.
FIG. 12 is an elevational view of the molding apparatus for the
molding M.sub.2, wherein a molding die 25 is provided with an
extrusion molding port 26 substantially corresponding in
configuration to the section of the side molding M.sub.2 a. The
molding die 25 is formed with a shutter 27 for varying the wall
thickness of the ornamental portion 2 of the molding M.sub.2 by
means of a drive motor 28 and a conversion mechanism 29 for
converting rotational movement to linear movement, the shutter 27
being linearly movable along the direction P corresponding to the
wall thickness of the ornamental portion 2. The positions of the
shutter 27 shown by a continuous line and a two-dot chain line
refer to the positions thereof for extruding the side molding
M.sub.2 a and the upper molding M.sub.2 b, respectively. Numeral 30
in FIG. 12 denotes a shutter guide for guiding the linear movement
of the shutter 27.
FIGS. 13 to 17, inclusive, show still another molding M.sub.3 and
its molding apparatus embodying the present invention.
Each of the side and upper moldings M.sub.3 a, M.sub.3 b comprises
a leg portion 31 and an ornamental portion 32 monolithically molded
at the upper end of the leg portion 31. However, the wall
thicknesses T.sub.3 a, T.sub.3 b of the respective ornamental
portions 32 differ from each other (see FIGS. 14 and 15). The leg
portion 31 of the side molding M.sub.3 a and that of the upper
molding M.sub.3 b are fitted into the gap formed between the
peripheral edge of the front glass 10 and the body panel 5 of the
window frame, whereas the ornamental portions 32 cover the gap
9.
As shown in FIGS. 14 and 15, a holding lip 33 is projected from the
inside of the lower end of the leg portion 31 of the side molding
M.sub.3 a, whereas a panel lip 34 is projected from the outside
thereof. A groove lip 35 is projected from the inside of the
ornamental portion 32, whereas an ornamental lip 36 is projected
from the outside thereof. With the ornamental portion 32 located to
the inside of the leg portion 31 and the holding lip 33, the side
molding M.sub.3 a is held and fitted against the side of the front
glass 10. The panel lip 34 resiliently contacts the tilted portion
5a of the body panel 5, whereas the ornamental lip 36 resiliently
contacts the upper face of the body panel 5. Moreover, a rainwater
guide groove 37 is formed between the surfaces of the front glass
10 and the groove lip 35. As shown in FIGS. 14 and 15, the wall
thickness T.sub.3 b of the ornamental portion 32 of the upper
molding M.sub.3 b is smaller than that of the side molding M.sub.3
a. The groove lip 35 of the upper molding M.sub.3 b resiliently
contacts the upper face of the front glass 10. Such that no
rainwater guide groove 37 is formed between the front glass 10 and
the groove lip 35 of the upper molding M.sub.3 b. The upper molding
M.sub.3 b includes the holding lip 33 and the panel lip 34 in a
like manner to the side molding M.sub.3 a, as shown in FIG. 15.
With the holding lip 33 and the ornamental portion 32, the upper
molding M.sub.3 b is held at the peripheral edge of the front glass
10.
As shown in FIG. 13, the wall thickness of the ornamental portion
32 of the side molding M.sub.3 a is made gradually smaller toward
the upper molding M.sub.3 b in the corner portion M.sub.3 c of the
molding M.sub.3. The width of the ornamental portion 32 is
simultaneously made gradually smaller toward the upper molding
M.sub.3 b. For this reason, the rainwater guide groove 37 is made
gradually narrower and disappears when it joins the upper molding
M.sub.3 b.
The molding M.sub.3 may be inserted in the window frame while
fitted with the front glass 10 or it may otherwise be inserted
after the front glass 10 is inserted in the window frame. In either
case, the molding M.sub.3 can be inserted stably in the window
frame since the panel lip 34 is arranged so as to resiliently
contact the tilted portion 5.sub.a of the body panel 5.
A reinforcing core material 38 is embedded in the leg portion 31 of
the molding M.sub.3, and an ornamental tape 39 is bonded to the
upper face of the ornamental portion 32.
The molding apparatus for the molding M.sub.3 will be described
with reference to FIGS. 16 and 17.
A molding die 41 is provided with an extrusion molding port 42
substantially corresponding to the section of the side molding
M.sub.3 a. A first and a second shutter 43, 44 are provided in the
front portion of the molding die 41 in such a way as to partially
cover the extrusion molding port 42. The first shutter 43 is fitted
so that it is linearly movable along the longitudinal direction of
an opening 42a for extruding the leg portion 31 of the molding
M.sub.3 out of the extrusion molding port 42, whereas the second
shutter 44 is fitted so that it is linearly movable along the
longitudinal direction of an opening 42b for extruding the
ornamental lip 39 of the molding M.sub.3 out of the extrusion
molding port 42. The shutters 43, 44 are linearly guided by
respective shutter guides 45, 46 and are provided with drive motors
47, 48 and conversion mechanisms 49, 51 for converting rotational
movements to linear movements, respectively. In this case, each of
the openings 42c, 42d for molding the holding lip 33 and the panel
lip 34 is formed in the first shutter 43.
The positions of the shutter for extruding the side molding M.sub.3
a are shown by a continuous line in FIG. 16, whereas the positions
of the shutter for extruding the upper molding M.sub.3 b are shown
by a two-dot chain line in FIG. 16 and a continuous line in FIG.
17. When the corner portion of the molding M.sub.3 is molded, the
first and the second shutter 43, 44 are linearly moved in the
predetermined direction as stated above to change the configuration
of the extrusion molding port 42.
FIGS. 18 and 19 show still another molding M.sub.4 embodying the
present invention. A description will subsequently be given of only
what is different from the molding M.sub.3 described above.
The molding M.sub.4 is fitted into the gap formed between the front
glass 10 and a fastener 53 secured via a double-sided tape 52 to
the inside of the tilted portion 5a of the body panel 5. A holding
lip 33' is projected inwardly from the lower end of the leg portion
31 of the molding M.sub.4, whereas a panel lip 34' is projected
outwardly from the opposite side of the holding lip 33'. A
projection 54 is provided at the leading end of the panel lip 34'.
When the panel lip 34' is made to resiliently contact the fastener
53, the projection 54 extended from the panel lip 34' engages with
a rugged portion 55 of the fastener 53, whereby the molding M.sub.4
is prevented from slipping out.
Referring now in general to all of the above-described embodiments,
the molding according to the present invention can be generally
defined as having an upper molding and side moldings, each of which
includes a leg portion which is disposed outwardly of and along the
peripheral edge of the windshield and a head portion which extends
inwardly from the leg portion and overlies the windshield (see
especially FIGS. 3, 4, 10, 11, 14, 15, 18 and 19). As shown in
these figures, the head portions of the side moldings (see FIGS. 3,
10, 14 and 18) are greater in thickness than the head portion of
the upper molding (see FIGS. 4, 11, 15 and 19), and the thickness
of the side molding head portions decreases toward the upper
molding. The head portions of the side moldings and upper molding
respectively have contacting surfaces which, as shown in FIGS. 2-4,
9-11, 13-15, 18 and 19, contact the exterior surface of the
windshield. As shown best in FIGS. 2, 9, and 13, the contacting
surface of the head portion of the upper molding runs continuous
with the contacting surfaces of the head portions of the side
moldings so as to define a single continuous surface contacting the
exterior surface of the windshield.
